SA1(8)                     Linux User's Manual                    SA1(8)

NAME         top

       sa1 - Collect and store binary data in the system activity daily
       data file.

SYNOPSIS         top

       /usr/local/lib64/sa/sa1 [ --boot | --rotate [ iso ] | --sleep |
       interval count ]

DESCRIPTION         top

       The sa1 command is a shell procedure variant of the sadc command
       and handles all of the flags and parameters of that command. The
       sa1 command collects and stores binary data in the current
       standard system activity daily data file.

       The standard system activity daily data file is named saDD unless
       sadc's option -D is used, in which case its name is saYYYYMMDD,
       where YYYY stands for the current year, MM for the current month
       and DD for the current day. By default it is located in the
       /var/log/sa directory.

       The interval and count parameters specify that the record should
       be written count times at interval seconds. If no arguments are
       given to sa1 then a single record is written.

       The sa1 command is designed to be started automatically by the
       cron command.

OPTIONS         top

       --boot This option tells sa1 that the sadc command should be
              called without specifying the interval and count
              parameters in order to insert a dummy record, marking the
              time when the counters restart from 0.

       --rotate [ iso ]
              Use this option to tell sa1 to insert a record of
              statistics to the standard saDD system activity daily data
              file of the previous day.  This should be done shortly
              after midnight (on day DD+1) in order to make sure that
              the data file covers the whole day, including the last
              interval of time just before midnight.  Adding the iso
              keyword tells sa1 to use saYYYYMMDD instead of saDD as the
              standard system activity daily data file name.

       --sleep
              This option tells sa1 that the sadc command should insert
              a comment indicating that the system is entering or
              leaving sleep mode (i.e. system suspend or hibernation).

EXAMPLE         top

       To collect data (including those from disks) every 10 minutes,
       place the following entry in your root crontab file:

       0,10,20,30,40,50 * * * * /usr/local/lib64/sa/sa1 1 1 -S DISK

       To rotate current system activity daily data file, ensuring it is
       complete, place the following entry in your root crontab file:

       0 0 * * * /usr/local/lib64/sa/sa1 --rotate

FILES         top

       /var/log/sa/saDD
       /var/log/sa/saYYYYMMDD
              The standard system activity daily data files and their
              default location.  YYYY stands for the current year, MM
              for the current month and DD for the current day.
